论文摘要
纠缠光子纠缠状态的制备对于量子计算和通信很有用。在本文中，我们使用具有适当反射率的光束拆分器提出了一种简单的纠缠产生方案。具有完全经典概率分布的初始状态的光子通过光学网络，由顺序梁拆分器组成，并以最大纠缠的状态制备。我们还为任意数量的光子介绍了纠缠状态生成的详细理论分析，这些光子以相等的概率通过梁拆分器的输入端口供电。
Preparation of entangled states of photons are useful for quantum computing and communication. In this paper, we present a simplistic protocol of entanglement generation using beam splitters with suitable reflectivity. The photons in an initial state with fully classical probability distribution pass through an optical network, made up of sequential beam splitters and are prepared in maximally entangled states. We also present the detailed theoretical analysis of entangled state generation, for an arbitrary number of photons, fed through the input ports of the beam splitters with equal probability.
